DESCRIPTION:I present a unified approach to calculating the next-to-next-t
 o-leading order (NNLO) soft and virtual QCD corrections to cross sections 
 for electroweak\, Higgs\, QCD\, and SUSY processes. I derive master formul
 as that can be used for any of these processes in hadron-hadron and lepton
 -hadron collisions. The formulas are based on a unified threshold resummat
 ion formalism and can be applied to both total and differential cross sect
 ions for processes with either simple or complex color flows and for vario
 us factorization schemes and kinematics. As a test of the formalism\, I re
 derive known NNLO results for Drell-Yan and Higgs production\, deep inelas
 tic scattering\, and W+ gamma production\, and I obtain expressions for se
 veral two-loop anomalous dimensions and other quantities needed in next-to
 -next-to-leading-logarithm (NNLL) resummations. I also present new results
  for the production of supersymmetric charged Higgs bosons\; massive elect
 roweak vector bosons\; photons\; heavy quarks in lepton-hadron and hadron-
 hadron collisions and in flavor-changing neutral current processes\; jets\
 ; and squarks and gluinos. The NNLO soft and virtual corrections are often
  dominant\, especially near threshold. Thus\, a unified approach to these 
 corrections is important in the search for new physics at present and futu
 re colliders.\n\nhttps://indico.ific.uv.es/event/1322/
